Yeah ECS is a pretty much just a dumb layer on top of docker that handles two things: placing your containers onto instances (and restarting them or replacing them if needed), and adjusting the settings on an ELB, or ALB so that the load balancer is pointed at an instance running the container. The ECS approach is a pretty minimal to glue together a cluster of instances running docker and ELB, while Kubernetes has a lot more baked into the core implementation.
